Why Choose the P12-300SB-PR

Customers have always been interested in the performance of the 300W Monolith Subwoofer, but some have been put of by the size. To get close to the performance of the Monolith we have designed the P12-300SB-PR a 50 litre enclosure incorporating a 12" driven element and a 12" passive radiator making a drive area of a massive 17". Powered by our 300W amplifier you also get class leading connectivity including in high and low level inputs with separate volume controls, filter by-pass on low level input, adjustable frequency 40 to 120Hz, continually variable phase 0 to 180 deg, automatic speaker protect and last but not least an Auto-On feature than can be switched off if you prefer. All this adds up to an extremely flexible and powerful subwoofer which will add great effects for movies and fill in the lower octaves for music

B.K. Electronics have been manufacturing subwoofers for over 20 years making us one of the most experienced subwoofer manufacturers in the world today. Thanks to our extensive range of subwoofers, whether using the low level input to add the all important LFE to today's blockbusters or to enhance or underpin the performance of a 2 channel music system thanks to BK's Hi Level input, we really have got all basses covered.

B.K. Electronics are pleased to announce their newest subwoofer the stunning Platinum P12-300SB. Boasting a 300W RMS (600W peak) amplifier coupled to a 12" long throw drive unit in a sealed enclosure to produce a deep, musical and dynamic subwoofer that can not only shake the room when required but can be subtle and refined, making the P12- 300SB the ideal subwoofer for both Hi-Fi and movies.

The P12-300SB comes fitted with high and low level inputs which have individual volume controls, a frequency adjustment that can be by-passed on the low level input for LFE use and a continuous 0 to 180 deg phase control. All these features make the P12-300SB extremely flexible making it easy to integrate into any Hi-Fi system, home cinema system or even both at the same time.

Not only does the P12-300SB have class leading control and connectivity it also comes supplied with an Auto On /Off feature, that switches the subwoofer into standby after 10 minutes of inactivity and instantly switches back on again when it senses a signal on any of its inputs. If you do not like the Auto-On / Off feature then this can be de-activated by toggle switch so that the subwoofer remains switched on until turned off by the main power switch
